i'm confused and don't know what to do

P: 20
i have developed a log in system which is a starting point for my online learning system i'm developing.
i'm failing to log in possibly the system is not able to register a user as a valid user.The system is not reflecting error warnings.
Here is a code section where i'm suspecting a fault.

function login($username, $passwd)
// check username and password with db
// if yes, return true
// else return false
// connect to db
$conn = db_connect();
if (!$conn)
return 0;

// check if username is unique
$result = mysql_query("select * from users
where username = '$username'
and passwd = '$passwd'");
if (!$result)
return 0;

if (mysql_num_rows($result)>0)
return 1;
return 0;

function check_valid_user()
// see if somebody is logged in and notify them if not
global $valid_user;
if (session_is_registered("valid_user"))
echo "Logged in as $valid_user.";
echo "<br>";
// they are not logged in
echo "You are not logged in.Please try again.<br>";
do_html_url("login.php", "Login");

// include function files for this application
if (isset($username) && isset($passwd))
// they have just tried logging in
if (login($username, $passwd))
// if they are in the database register the user id
$valid_user = $username;
// give menu of options

Please help to get out of this situation
